I’m not asking this to be condescending, but have you ever felt cold?
My hands lose all dexterity entirely in winter. With sufficiently cold weather my hands are either cold, stiff, and in pain, or I’m wearing gloves that are too bulky to be useful for anything other than crudely gripping large objects or swatting things away. These people are experiencing cold beyond what I’ve ever experienced, so I can’t even begin to imagine how much worse it is.
If people are burning things for warmth, they are absolutely not going to be holding a needle.
well the article cites -20 I assume based on area F so ~ -7C
...really -7C is cold beyond what you ever experienced ? It's not too bad. I'd imagine the main problem is if those temperatures are rare just nobody have proper clothes to handle it
